Crushing Plant Design and Layout Considerations

As it turned out, designers are now adding secondary or pebble crushers to SAG circuits, on both greenfield and retrofit projects, to increase feed rate to the SAG mill In other words, crushing plants, from primary to quaternary circuits, are here to stay There are three main steps in designing a good crushing plant: process design, equipmentFoundation design for tucano gold project The Tucano project is located in Amapá State in northern Brazil This area has an equatorial climate, with yearround high humidity and rainfall Mean average precipitation is 2,387 mm Average annual evaporation is 1,400 mm Groundwater occurs at shallow depths (typically 05 to 30 m below ground level)SRK Consulting, Australia | Tucano Gold |
